CVE-2024-4258·PHP vulnerability

The Video Gallery – YouTube Playlist, Channel Gallery by YotuWP plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 1.3.13 via the settings parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.

What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

POST|GET requests to wp-admin or plugin configuration endpoints containing 'yotuwp.*settings' parameters with file path traversal sequences (../, ..\, or encoded variants); PHP error logs showing 'include' or 'require' statements with user-controlled paths; requests containing patterns like 'settings=../../../../etc/passwd' or similar LFI payloads

WAF mitigation (if patching is not yet possible)

Add this rule to your WAF to block exploitation attempts while you schedule the patch. 

Block or rate-limit requests to the YotuWP plugin settings endpoint that contain path traversal characters (../, ..\ , %2e%2e%2f) in the 'settings' parameter; implement input validation rules that restrict settings parameter to whitelisted alphanumeric values only

How to check if you are affected

  1. Check installed PHP version: php -v
  2. List installed WordPress plugins: wp plugin list --allow-root (if wp-cli is available) or check /wp-content/plugins/ directory for 'yotuwp-easy-youtube-embed' folder
  3. Verify plugin version: grep -r 'Version:' /wp-content/plugins/yotuwp-easy-youtube-embed/ | head -1
  4. Confirm patch applied: Verify plugin version is 1.3.14 or higher and check file modification times of yotuwp.php around line 731 match recent updates

CVE-2025-46348CVSS 10YesWiki is a wiki system written in PHP. Prior to version 4.5.4, the request to commence a site backup can be performed and downloaded without authentication. The archives are created with a predictable filename, so a malicious user could create and download an archive without being authenticated. This could result in a malicious attacker making numerous requests to create archives and fill up the file system, or by downloading the archive which contains sensitive site information. This issue has been patched in version 4.5.4.
CVE-2026-39337CVSS 10ChurchCRM is an open-source church management system. Prior to 7.1.0, critical pre-authentication remote code execution vulnerability in ChurchCRM's setup wizard allows unauthenticated attackers to inject arbitrary PHP code during the initial installation process, leading to complete server compromise. The "$dbPassword" variable is not sanitized. This vulnerability exists due to an incomplete fix for CVE-2025-62521. This vulnerability is fixed in 7.1.0.
CVE-2025-62521CVSS 10ChurchCRM is an open-source church management system. Prior to version 5.21.0, a pre-authentication remote code execution vulnerability in ChurchCRM's setup wizard allows unauthenticated attackers to inject arbitrary PHP code during the initial installation process, leading to complete server compromise. The vulnerability exists in `setup/routes/setup.php` where user input from the setup form is directly concatenated into a PHP configuration template without any validation or sanitization. Any parameter in the setup form can be used to inject PHP code that gets written to `Include/Config.php`, which is then executed on every page load. This is more severe than typical authenticated RCE vulnerabilities because it requires no credentials and affects the installation process that administrators must complete. Version 5.21.0 patches the issue.
CVE-2024-5932CVSS 10The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.14.1 via deserialization of untrusted input from the 'give_title' parameter. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to execute code remotely, and to delete arbitrary files.
